Shingles; lnade of sniitablc relatively tier-- ible waterproof materialand formed to be laid in such manner that the lower entrenoities of theexposed portions; are each provided with a single anchoring flap or tab,are well known and have gone inte extensive use. Although such shinglesare widely used they are open to the objection that the tabs,particularly vvlien softened by surn- :lner heat7 are easily bent backon tljlcinselves cr torn 'while being` forced into position partlyunderneath previously laid shingles and are not stili enough to retaintheir hold and satisfactorily perform their anchoring function. In othertypes in which depend ence ie placed cn a wire atlired to each tab andhaviiin; laterally extended end ncrticns arranged to be insertedbeneaththe cdn'ee of pri-iviously laid ehingrlea tbe small :were ci contact ofthe wire sections with the laterally dianosed anchoring.: Shingles doesnot aeclnfely hold the overlying; shingle in flat position. and alsotends to out and tear the anchor-inn; shingles under the :fiction ofwind and weather and the tendency to warp and curl which is inherent inthe shingles thcrnselves.

An object of the present invention is to provide a sl'lingleminstrueticn of the inter- .h .hing type which will be free from tbeobjections referred to and in which the errposed end of the shingle isseci'xl'ely an chcred in flat position to tbc underlying shingles.

another featijlre of the invention resides in the provision of twoanchoring; tabs, instead of one. formed at the lcwermost ccrner of theshingle. rFhis construction provides for the insertion of the entirearea of each tab beneath the flanking (fliagcnal man gin of a previouslylaid shingle to obtain a correspondingly increased anchoring enrangementtherewith. The two tabs are formed to extend diagonally away fromeacl'i. other in upward and outward directions and are supplied with thereinforcingl clips referred tc sc that they produce an exceedinglyeffective holding1 engagement between the two layers of shingle units.

Other features ofthe invention. will be hereinafter referred to.

Referring to the drawings for a more de Gti tailed description of theinvention a. shingle 5 is shown which may be formed of asphaltum-treatedfibrous matter or other material suitable `for the purpose. rl`heshingles shown are intended to be applied to the desired surface in suchmanner that side edges of the weather-exposed port, nz of the shinglestake downwardly converging positions and form diagonale with relation tothe horizontal. The lowermost corner or extremity of each shingle isslit as at 6 and then turned under and folded back to form a pair oi"tabs or tongues 7 adapted to be inserted `for their full length beneathf the flanking edges of the two 'iuxtaposed underlying shingles FS and 9as indicated in Figure 1 of the drawing.

Experience has shown that relatively flexible anchoring tabs such as areformed by turning back on themselves corner extremities of asphaltshingles, tend to bend and fold in the act of pushing them to placebeneath the edges oit' previously laid shingles It has also been foundthat the line of attachment between the underturned tab and the mainbody portion of the shingle is not strong enough to invariably resistthe strain of pushing thev tabs to anchoring position or the liftingforce exerted on the overlying shingle through the action of windblowing beneath the edges of the shingles beneath, with the result thatthe lower extremities of the shingles are occasionally torn from theirconnection to the anchoring tabs.

I overcome these objections by the use of a reinforcing clip member 10which is formed of sheet 'metal and attached in any con venient manner,as by means of tongues 1'1 'formed in the body of the strip, to onesurface of each of the tab members 7 as in Figure 2 of the drawing. Thetab members 7 are then turned back as in. Figure 3 which causes themetal .st-rips 10 to be folded back on themselves as shown in Figures 3and 5 to provide clip or holder whose opp'ositely disposed members are'spaced apart by the thickness of a. shingle.

In practice, the tab members T are pushed upwardly and for 4their fulllength beneath the edges oi two adjacent shingles as 8 and 9 in Figure'l of the drawings. The pushing oit' the tabs into place beneath theshingles 8 and 9 greatly Vfacilitated by reason ot the reinforcingmembers 10 whose stillness 'prevents the buckling or bending of thetabs. lVhen `the tabs are in position beneath the shingles 8 and 9 itwill be seen that the lower arm ofthe clip engages the lower surface ofthe shingle while the upper arm engages the upper surface of the lowershingles and rests against' the lower surface of the over-lying shingleby which the tab and clip' are carried. The clip member thus holds orclamps the anchoring shingles' and holds the overlying shingle in a'stable, flat position. It will be clear that additional fastening meansmay be employed as the use of nails in protected locations for .securelyattaching the shingles in place.

ln Figure -fl of the drawings a modified form 'of the invention is shownin which the tab members 12 have a somewhat different Vformation than inFigure 3 so that the side edges of the tabs and the lower arms of thecorrespondingly modified clip 13 take positions parallel to the verticalaxis of the shingle so as to' facilitate the pushing of the shinglealong its vertical axis into position.

In Figure 'i' is shown a construction in which the reinforcing member 14extends to the lateral edges of the tab and rewardly along the undersurface of the shingle beyond the line of bend, thereby providing anextremely effective and secure anchoring device.

It will be seen that I have thus provided a shingle construction havingdouble interlocking or reinforcing tabs' provided with reinforcing clipsextending longitudinally o'l'i the tabs and formed to engage bethsurfaces of underlying shingles, and the' Whole area of the anchoringtabs being el'ecti've to engage the lower surface of underlyingvshingles to securely hold the overlying shin'- gle in flat position.

What I claim is 1. In a shingle of the interlocking type, a lower cornerof the shingle being slit to form a pair of tab members, said tabmembers ibeing bent upwardly and outwardly from the slit for insertionbeneath previously laid shingles, and reinforcing members carried by thetabs for engagement with both the upper and lower surfaces of thepreviously laid shingles.

2. In a shingle of the interlocking type, a margin of the shingle beingformed into underturned tab members for anchoring' engagement with theunder surface of previous'ly laid shingles; and Sheet' metal reinforcing members attached to the upper' suri' ace of the tab members.

3.

4. In a shingle of the interlocking type, a corner of the shingle being'formed into a pair of underturn'e'd tab members for amchoringengagement' with the under' surface of previously-laid shingles', andm'til reinforcing members attached to' the't up'per surface of the tabsand bent' back along" the under Surface of the shingle' bo'eei've theumdeyng hing-glu@ 'g1/n Langage, mtfll Hw u [3 per :md 10W-31.' mmfaca@thereof.
